Variable Power supply

Just wondering if any one could give me some insight on this power supply.

I currently have a Astron RS-50A and what i would like to do is make the Voltage and current variable. There is another model VS-50M which has these options. I kindly asked the manufacturer for the schematics and they were nice enough to send them. From the schematics they look very similar except for a few minor things. So my question is. Would it be as simple as just adding the two missing potentiometers that are located on the VS-50M? Below i have added a link for the drawings and highlighted everything in red that is different and green is the same. If this just makes it more confusing i can upload the originals with no markings. Reasoning for wanting variable voltage and current is that i use it for plating/anodizing metals. Any help would be much appreciated.

Yes, just add the missing pots and it should be fine.

Thanks for the quick reply. Didn't have any potentiometers at home that would work so i had to order. Hopefully i will get them sometime next week.

Thanks again,
